The interview was taken inside the Tropenmuseum with Rene Boer, an urban researcher and writer based in Amsterdam. We discussed about his research collective called "failed architecture". The discussion went further to the notion of "ruin" as a critical entry point in questioning architecture in its relation to power structure. The discussion was followed by unveiling the notion of appropriation through his squatting practice either in Amsterdam context and its critical dimension at looking archives in museal context. Concept of appropriation led us to unavoidable dimension of spatiality of the colonial archive and the question of contemporariness on heritage.
